我在markdown中有一个小的文本文件:
---
title: postWithReference
author: auf
date: 2010-07-29
keywords: homepage
abstract: |
What are the objects of
ontologists .
bibliography: "/home/frank/Workspace8/SSG/site/resources/BibTexLatex.bib"
csl: "/home/frank/Workspace8/SSG/site/resources/chicago-fullnote-bibliography-bb.csl"
---
An example post. With a reference to [@Frank2010a] and more[@navratil08].

并在Haskell中使用processCites'
对其进行处理,其中Pandoc
具有单个参数,即readMarkdown
产生的processCites
数据。参考书目和csl样式应从输入文件中获取。
该过程不会产生错误,但是pandoc -f markdown -t html --filter=pandoc-citeproc -o p1.html postWithReference.md
的结果与输入内容相同;引用完全不被处理。对于相同的输入,引用由独立的pandoc解析(这不包括书目和csl样式中的错误)
markdownToHTML4 :: Text -> PandocIO Value
markdownToHTML4 t = do
pandoc <- readMarkdown markdownOptions t
let meta2 = flattenMeta (getMeta pandoc)
-- test if biblio is present and apply
let bib = Just $ ( meta2) ^? key "bibliography" . _String
pandoc2 <- case bib of
Nothing -> return pandoc
_ -> do
res <- liftIO $ processCites' pandoc -- :: Pandoc -> IO Pandoc
when (res == pandoc) $
liftIO $ putStrLn "*** markdownToHTML3 result without references ***"
return res
htmltex <- writeHtml5String html5Options pandoc2
let withContent = ( meta2) & _Object . at "contentHtml" ?~ String ( htmltex)
return withContent
getMeta :: Pandoc -> Meta
getMeta (Pandoc m _) = m
因此,问题出在API中。我的代码是:
-- We need to know the citation keys, add then *before* actually parsing the
-- actual page. If we don't do this, pandoc won't even consider them
-- citations!
我误解了什么? citeproc是否需要阅读器选项?参考书目是一个BibLatex文件。
我在hakyll code中发现了一条注释,根据那里的代码,我无法理解该注释-也许有人知道意图是什么。
="select 'foo' as Foo"

我有一个解决方法(不是原始问题的答案,我仍然希望有人可以识别我的错误!)。用pandoc
调用独立的System.readProess
很简单,并传递文本并返回结果,甚至不读写文件:
processCites2x :: Maybe FilePath -> Maybe FilePath -> Text -> ErrIO Text
-- porcess the cites in the text (not with the API)
-- using systemcall because the standalone pandoc works with
-- call: pandoc -f markdown -t html --filter=pandoc-citeproc
-- with the input text on stdin and the result on stdout
-- the csl and bib file are used from text, not from what is in the arguments
processCites2x _ _ t = do
putIOwords ["processCite2" ] -- - filein\n", showT styleFn2, "\n", showT bibfn2]
let cmd = "pandoc"
let cmdargs = ["--from=markdown", "--to=html5", "--filter=pandoc-citeproc" ]
let cmdinp = t2s t
res :: String <- callIO $ System.readProcess cmd cmdargs cmdinp
return . s2t $ res
-- error are properly caught and reported in ErrIO
t2s
和s2t
是字符串和文本之间的转换实用程序,ErrIO
是ErrorT Text a IO
,而callIO
实际上是liftIO
,具有错误处理功能。

最初的问题非常简单:我没有在Ext_citations
中包括选项markdownOptions
。包含该示例后,该示例将起作用(感谢我从pandoc-citeproc
问题页面获得的帮助)。引用的代码已更新...
